On December 18, 2011, the WPFM Honor Guard had the privilege of presenting the colors and piping at the 20th anniversary memorial service to remember the four firefighters who passed away in the Line of Duty from Hill Top Hose Company No. 3, Harrison Township, Allegheny County. The members of the WPFMHG thank Hill Top Hose for having us with them today and we will always hold true this dark day in Allegheny County Fire Service history. Lest We Forget - December 20, 1991.
